WHAT’S BEING CLAIMED:
- General Motors announced Thursday it is recalling 638,000 U.S. sport utility vehicles and pickup trucks due to possible wheel-speed sensor failure which can cause unintended braking.
- Affected by the recall are some of the company’s most popular trucks and SUVs, including the 2014-2018 , 2015-2020 and , 2014-2018 and 2015-2020
- Owners of the affected Chevy and GMC models will be notified by the automaker via mail, though GM hasn’t announced a schedule yet.
General Motors announced a new recall on Thursday affecting hundreds of thousands of Chevy and GMC pickup trucks and SUVs. The automaker filed the recall with the National Highway Traffic Safety Administration declaring software error can cause unintended braking.
Here’s the list of GM’s trucks and SUVs included in the recall: The 2014-2018, 2015-2020 and , 2014-2018 and 2015-2020 All these popular models mentioned may house faulty electronic brake control module software.
The recall affects 638,000 vehicles. The automaker added the problem affects only SUVs and trucks with a 5.3-liter V8 engine, 3.08-ratio rear axle and four-wheel drive. A wheel-speed sensor failure may not play nice with the wonky software, and the driveline-protection system could activate, GM said.
If it does activate, drivers will experience unexpected braking from the wheel opposite the wheel that houses the failed speed sensor. This can happen when a driver opts for four-wheel-drive or travels between 41 mph and 60 mph, according to GM. Additionally, the brake control modules in affected Chevy and GMC vehicles have incorrect axle-ratio calibrations. This can lead to the inability to properly calculate wheel speed, therefore, unlock issues with the driveline-protection system. The vehicle may pull to one side unexpectedly if the unintended braking occurs, increasing the risk of a crash.
GM added that if a wheel-speed sensor fails, drivers will see the electronic stability control and antilock brake lights (ESC and ABS) light up on the dashboard. There will be a message that reads: “Service StabiliTrak.” Drivers can eliminate the risk by avoiding to put their truck or SUV in four-wheel-drive mode before the recall repair.
The company will notify owners of the affected Chevy and GMC models via mail, though it’s not clear what the schedule is. To address the issue, a technician will reprogram the EBCM for free.
